Theprime object of this invention ist@ pro-v vide means consisting of a method and appa ratus for treating boiler water, to be pret erably ealled the Elgin' gravity system for Continuously' treating boiler Water, for softening and purifying purposes -While the boiler vis in operation.

i Another object of this invention is to pro vide suitable apparatus or means for admit ting chemical treatment the required treatment having been deteaj mined by some suitable test, suoli as the Elgin method otesting and treating boiler pater in order to ascertain the kindv and quantity of treatment required. Obviously, however, the apparatus herewith invented for supplying required chemical treatment to theboiler w'a- .Y ter is not confined in use to any one method for determining the required treatment.

In the drawing, the single figure illustrates a view in elevation of treatment tanks, mixing tank, steam pump and fittings in typical assembled relation to a boiler. Y

In a typical arrangement, numeral l desig nates the steam line to the mixing tank, and .2 the Water line, While 3 leadslto the suction pump 7. The siphon i extends into the mixing tank 5, and hinged lid G is a cover on the mixing tank 5. The numeral 9 represents the discharge from the steam pump to pressure treatment tanks D or E. Numerals l0 and 11 designate the -valves to the gravity pressure tanks E and D, While the valve 12 leads from the gravity tank D to the treatment regulating needle point valve D', and 13 represents the valve leading from the gravity tank -E to the regulating needle point valve E.

The numeral let designates the valve con- 4o nesting the steam boiler pressure with tank D, and 15 the valve connecting steam boiler pressure 'with tank E, While 16 represents the cheek valves to prevent flow of treatment from D or E into the steam line. Numeral 17 designates the chain wheels to operate valves 14 and 15 to `steam supply from the floor, while 18 is .the steam line leadingr to the steam pressure supply, and numerals 19 to 25, inclusive, represent the treatment lines leading to the different boilers. Numerals 32 and 33 in the drawings designate diagrammatie views of boilers adapted to be operato the boiler 26 represents a pressure gauge, and 2l' a retively oonneeted to the treatment lines 24 and 25, it being understoodlthat individual boilers 'may be vconnected to the lines 19 and 23 ir a similar manner. M a matter of feet any number of treatment lines or boilers may be attached to this system Without aieeting the merits oi this invention. bviously, the D needle point valves will supply D treatment to any boiler while in operation, and. in any quantity desired., While l needle point valves 'are adapted to supply E treatment to any boiler many desired quantity. The numeral il' lief valve, While 28 and 29 designate a globe stop valve, and an air pet oook.V The pipe leading to the mixing tank is designated by the numeral 30, and 31 is a sieve.

When valves 14 and l5 are closed, also valves 11, 1 2 andr 13. Chemicals are then deposited in mixing tank` 5 through cover 6, and water is introduced into the tank through valve 2, to ai point extending Well over the mining Siphon e. The Water valve 2 is then closed, and steam valve l opened thereby, admitting steam into the tank which thorn oughly agitates, dissolves and mixes the chemicals with the Water. The valve 1 is then j closed and 2 opened, iilling the. tank to any au desired point, after which valves 3,:9 and 1G. may be opened, andftheli uid chemical treatd ment/pumped by means o pump 7 from tank 5, through these open valves into tank E, when the mixing tank 5 is empty valve l() may be closed.

The ehemieals for D treatment are then put in the mixing tank 5 as'b'eiore,'and 'when thoroughly mined, valve 1l must be opened se thatathe liquid may he pumped to tank D.

When the mixing tank is aga-in empty tank D should be full, then valve 11 must be closed., and the tanks D and E now being illed With ehemiealized liquid treatment the system is ready for admitting the treatment 'from the" dinmerent tanks to the boiler Water in estimated proportion for `softening,the water to i y the desired point., This proportion may be obtained by different methods, preferably by the applieants @pending-application, on a 10e -rneans and process for treating boiler wete in order to ascertain the kinl and cpiantityv of treatment required. in oder to admit treatment 'from the diierent gravity tanks to from one quarter to one half turn.

the boiler, valves 13, 14 and 15 are opened, ad mitting treatment low throu h the line to all valves marked E', for exam e, to treat Water in boiler 25, the needle vaA ve E is opened The liq uid will then flow by avity through valve E and pipe 25 to the oilerjust in proportion to the opening ot the' valve.

lf the test of the boiler waterv shows that more D treatment is required then valved is ope ed lettin the liquid ow 1n the line from D tank uni. er all the valves marked IY, then open the D valve on line 25one quarter Ito one half turn, letting some l) treatment flow through pipe 25 to boiler. The D and la' valves on line 25 nowl both being opened a small amount, the treatment can be adjusted through the D and E valve to get any desired strength on the D and test. lihe D and E valves may' be entirely closed it nec essary, should either treatment be too strong. This same operation will apply on the D and E valves to any line, as for instance, 19 to 25, inclusive, leading to boilers, and the water can be treated continuously to any degree of hardness. i i

To refill D tank close chain valve le and valve 12, also valve 9, then open valve li, 28 and air cock 29. This will let tank' D relieve its pressure with any condensed Water therein through the mixin r tank 5, after which more chemicals are p aced in the tank and mixed as betere. In refilling either D or E tank valves 14 and 15 in steam supply line should be closed, also valves 12 and 18;

Either one of these tanks may be filled While the other is in operation. The manner of administering the treatment through pipe line 25 Will a )ply to any one of the other branch lines to different boilers.
